Car HD Radio with Bluetooth 5.0

The ESTONE BC71 is a car HD radio kit that connects to a factory stereo via FM transmission. It includes Bluetooth 5.0 for wireless audio streaming and hands-free calls, plus dual USB ports for charging devices. A digital display shows the FM status and vehicle voltage in real time.

Suits drivers adding Bluetooth

Buyers who want an integrated head unit with a built-in screen or native DAB+ reception should look at a different product type. This adapter relies on an empty FM frequency and does not replace the original radio.

36 W combined PD and QC3.0 charging

The unit delivers up to 18 W from the USB Type-C PD port and 18 W from the USB-A QC3.0 port simultaneously. This total output decides whether the BC71 can fast-charge two phones or a phone and a tablet at the same time.
